Yellow volume control

I'm using liberty 1.5 with the green gingerbread theme and love it. I should have rommed this phone sooner. My only complaint is that whenever I change the volume the on screen pop up is still yellow. I've got everything else customized in green and black (except for swype, but I'm working on that). Is there a way to change the color of this pop up or is there a black and green theme that has this change?

Thanks for any help. I read this forum daily but never post, keep up the good work!
